Same here.  No one on the other end.  Not sure what this was but I've been getting many of these lately. Other number doing the same thing are:
717-862-2376
385-498-5134
916-218-4831
775-297-8824
972-314-0355
704-307-4885

called 5 times yesterday, and today 3, so i picked up believing this was an urgent call and one of my kids were hurt, i picked up, said hello 4 times, nothing, in 40 sec time, and as i was hanging up, some one hello, how are you today... to late, blocked now
just another scammy spammer, on my paid for phone service,
i hate that i pay for a service and its used to abuse me - how messed up is that.

Unknown, unidentified number did not leave a message.  Now identified in my phone as DO NOT ANSWER.

I couldn't agree more. They called this afternoon, then called back 15 min later. I pay for phone service, I should be using it for MY benefit, not theirs. Any company making cold calls should be required to pay us for the use of our phone service.

Get your $250k business loan.  I get this call no less than 5 times a week.  A majority of the time I let them connect me to their overseas office just to troll on them.  I have to say I am getting sick of their crap.
